towards the rectangular hind angles; the deep median channel, which 

 is expanded behind, extends almost, or quite, from base to apex; at 

 each side of it, on the middle, there is a well-marked puncture, and a 

 smaller one near the apex ; basal fossae deep and moderately elongate, 

 with a transverse series of 6 punctures between them; along each side 

 from the posterior angle to beyond the middle there are several small 

 punctures; it bears numerous elongate ashy hairs. Elytra oblong-oval, 

 with curvedly narrowed shoulders, so that the base is only a little broader 

 than that of the thorax, which is hardly half their length; their sculp- 

 ture is irregular, consisting of, on each, 6 dorsal rows of very unequal 

 punctures, some are elongate or oblong and others very distant from 

 each other, just at the base some almost form striae; they are clothed 

 with suberect, very elongate, slender cinereous hairs, and many con- 

 spicuous white ones are intermingled. 



Antennae stout, finely setose; the basal six joints are subcylindric, 

 and differ but little, the 1st, however, is thicker, and the 6th rather 

 thinner than the contiguous ones; 7th rather broader than 6th; 8th 

 evidently the smallest; joints 9—11 about as broad as the 7th. 



Male. — Tarsi anterior, with the basal three articulations dilated, the 

 1st largest, intermediate pair simple, 5th ventral segment incurved at the 

 apex . 



Rather larger than G. thoracica (270), which, however, can be easily 

 recognized by the very regularly striate-punctate elytra and well-marked 

 interstices. 



I possess eight specimens of the present species; two were secured by 

 myself, the others were found in leaf-mould sent to me by Mr. W. J. 

 Guinness during March and April, 1910. They are very homogeneous.

3219. Silohotelus obliquus sp. nov. SUphotdus Broun, Ann. Mag. Nat, 

 Hist., ser. 6, vol. 15, p. 83. 



Glossy, oblong-oval, slightly convex, bearing only a few minute erect 

 grey setae; fuscous; sides of thorax and the shoulders of a paler and 

 more rufescent line; the sides of elytra behind the middle fusco- 

 testaceous. 



Head slightly broader than apex of thorax, very evidently and broadly 

 depressed between the vertex and the eyes, without visible sculpture. 

 Eyes nearly flat, occupying more than half of each side of the head, 

 just free from the thorax, truncate behind, narrowed anteriorly, with 

 moderate facets. Thorax transverse, the sides very distinctly margined, 

 gently ciirvedly narrowed towards the subtruncate apex ; the base closely 

 adapted to the elytra, feebly medially curved and sinuate towards the 

 sides, its angles just rectangular; its sculpture very fine and hardly 

 discernible. ScuteUum large, curvilinearly triangular. Elytra oblong, 

 just a little broader than thorax at the base, quite twice its length, 

 oblique towards the obtuse apices, the lateral margins much thinner than 

 those of the thorax; their punctation irregular, rather fine and shallow, 

 nowhere close, the suture sharply defined, with obsolete striae. 



Antennae inserted at the sides quite clear of the eyes; basal joint 

 cylindric, slightly longer than 2nd, both fusco-testaceous; 3rd more 

 slender than 2nd, and nearly as long as it is; joints 4—7 longer than 

 broad, and about equal: 8th slightly broader than 7th, not abbreviated;
